fin Sucker-Rod Connectors, of which the following is a specification.

This invention is an improved construction of sucker-rod couplingor connector, theob ject being to provide an exceedingly simple and 'highly-elcient coupling or connector,

whereby two sections of a sucker-rod may be quickly and easily connected or disconnected.

With this object in view the invention consists in the novel features of construction and combination and arrangement, and also in the novel construction of tool `-to be used in connection with the coupling, all of which will be fully described hereinafter, and pointed out in the claims. j

In the drawings forming part of this speciication, Figure lisa perspective view showing the coupling complete. Fig. 2 is a detail perspective view of the tool to be used in connection with the coupling. Fig. 3 is a vertical sectional View taken through the coupling, the tool beingshown in dotted lines. Fig. 4t is a detail perspective view of the socket. Fig. 5 is a detail perspective view of the head, and Fig. 6 is a detail perspective View of the wedge and? attached spring.

Referring to the drawings, A indicates one section of the sucker-rod and B the other section, said section A terminating in a socket C, having an opening D at one side adjacent to the top. The section B terminates in a head E, having a laterally-proj ectin g portion F, which is adapted to be projected into the opening D when the coupling or connecting operationis complete. The under side of the lateral extension F is beveled, as shown at F', and the lower edge of the opening D is beveled, as shown at D, the beveled face being` adapted to contact, 'as most clearly shown in.

Fig. 3. The bore of the socket is square in cross-section, and the head E is also square in cross-section; but the main portion of` said head is narrower than the `bore of the socket, but the extreme end, or that portion having the lateral extension or projection, is of substantially the same size as the bore of the Serial No. 112,92 2. (No model.)

socket. the socket the projection is forced into the opening D and the coupling is completed by means of the wedge G, which is forced up into thesocket alongside of the head, the head and adjacent portion of the sucker-rod being in alinement, as most clearly shown, ,thereby enabling the wedge to be pushed up into the socket7 forcing the lateral projection of the head into the opening D, and it will be noted that the said wedge is formed with an enlargement G adjacent to the upper end and a shoulder G2 at its lower end. A leaf-spring I-I is riveted to the inner face of the wedge G and carries a staple II adjacent to this lower end and upon the outer face.

I indicates a series of shoulders arranged in step order transversely across section of the sucker-rod a short distance below the head, the purpose of said steps being to serve as a stop against which the lower end of the spring rests when the coupling is completed. As before stated, the head is inserted into the socket and shifted laterally and wedge inserted, and the enlarged portion G will serve to hold the lateral' projection of the head always in close engagement with the opening latter from becoming loose, a band partly en- D. In order to disconnect the sections, I employ a tool K, comprising the shank K', shoulder K2, and finger K3, terminating in a point K4. The manner of using the tool is as follows:`

The point K4 is inserted in the shank H Of the spring and the shoulder K2 brought into engagement with the shoulder G2, and then by rocking'the tool upon the beveled'end A2 ofthe socket and pressing down upon the same the wedge is withdrawn from the socket and the parts can then be disconnected. The upper section of the coupling is preferably constructed to receivethe gripping-tools, by. means of which the rods can be withdrawn from the well or tubing, and it will thus be seen that I provide an exceedingly simple and highly-efficient construction of sucker-rod coupling or connection.

Having thus fully describediny invention, what I claim as new, andv desire to secureby Letters Patent, `is-` After the head has been inserted into 1. A device of the kind described compris ing a socket having an opening at one side, a head adapted to enter the socket and having a lateral projection or extension, a wedge adapted to be inserted within the socket and` alongside the head, and means attached to saidwedge for holding the same in position opening at one side, of a head carried at the upper end of the rod-section and having` a lateral extension, said rod-section having a series oi' transverse shoulders arranged below z the head, and a Wedge having a curved enlargement adjacent to its upper end, and a transverse shoulder adjacent to its lower end,

and a plate secured to the said wedge and extending below the same and carrying a staple idjacent to its lower end for the purpose speci- FRANCIS M. EGBERT.
